TAX1BP1 (Tax1 Binding Protein 1) is a ubiquitin-binding protein that plays critical roles in selective autophagy, NF-κB signaling, and innate immune responses. The gene encodes a 789 amino acid protein that serves as an autophagy receptor for damaged mitochondria and intracellular pathogens. TAX1BP1 is located on chromosome 7p15.2 and is expressed in various tissues with particularly high expression in immune cells and the brain. The protein contains multiple functional domains enabling its roles in ubiquitin recognition and autophagy regulation.
The TAX1BP1 gene spans approximately 30 kb and includes:
